Final answer:
The set of numbers written in order from least to greatest is a) 809,452 < 890,254 < 904,258 < 904,285. The other options incorrectly order the numbers.
Step-by-step explanation:
The student's question asks which set of numbers is written in order from least to greatest. The correct order from least to greatest should have the smallest number first and the largest number last. Comparing the options given:
- a) 809,452 < 890,254 < 904,258 < 904,285
- b) 809,452 < 890,254 < 904,285 < 904,258 (Incorrect as 904,285 is greater than 904,258)
- c) 890,254 < 809,452 < 904,258 < 904,285 (Incorrect as 809,452 is less than 890,254)
- d) 890,254 < 809,452 < 904,285 < 904,258 (Incorrect as 809,452 is less than 890,254 and 904,285 is greater than 904,258)
Therefore, the correct answer is:
a) 809,452 < 890,254 < 904,258 < 904,285
